Try using ImgBurn. You want to make sure you are burning the iso image to the cd. Explorer the cd you have already burned, if you see xxxx.iso, you burned the file to the cd and not the image. The imaged cd will show a lot of files.

If you use DSL, Dial UP or Comcast, you may have noise in the signals that
cause the file to corrupt.

Those methods all rely on electrical or cable connections that may be
susceptible to moisture or corrosion.

You may consider purchasing a CD from a vendor listed at the site. These
are physically stamped and not
"burned" like home CD's. They can be counted on for freedom from corruption
and this media works better
with older CD/DVD drives that may be out of tolerance or dirty.

An alternative, if it's a newer computer with a boot from USB option, would
be to use Source Forge's free program called Unetbootin
to create a bootable USB drive instead of using a CD or DVD. Since it
appears you are experiencing different
problems each time you try to install, I'd say it's a problem with your
CD/DVD or CD/DVD player.

CD and DVD drives may appear to work properly in everyday use, when you try
to install a 700 MB OS, errors
because of bad media, bad tolerances or dirt can cause erratic operation
resulting in different errors every time
you try to install it. If the error is consistent, then It's probably a
hardware or driver.issue.

For the past year I've been attempting to use samba shares as my
File-server for my Archives
it works great for about three weeks in a row, then Completely starts
ignoring my request
to View Files ignored any PC trying to Connect to it, through the
Workgroup eventually i have to reinstall Ubuntu 11.0
and it works great for 3 weeks again and this starts all over again,
anyone have any suggestions for me to try please let me
know , or ill go back to Windows server 2008

I think your config file have problem when start see /var/log/messages to which line have problem. If cant find erase in Redhat family with rpm -e samba and in debian family dpkg -e samba. After remove file from /etc/samba/smb.conf and after reinstall again.
